In the following description, a detailed structure will be presented for a thorough understanding of embodiments of the present utility model. It will be apparent that embodiments of the utility model may be practiced without limitation to the specific details that are set forth by those skilled in the art. Preferred embodiments of the present utility model are described in detail below, however, the present utility model may have other embodiments in addition to these detailed descriptions.

The present utility model provides a locking device 100. The locking device 100 can be used in a garage. The garage is of at least two-layer structure. Each floor is provided with a garage for storing vehicles. The garage also includes a vehicle loading platform 180 and a pedestrian platform 170. The garage has a floor (not shown). The floor separates different floors of the garage. The floor is provided with mounting holes (not shown). The mounting holes may be circular through holes.

Pedestrian platform 170 rotatably extends through the mounting hole. The axis of rotation of the people moving platform 170 is parallel to the vertical. Personnel may walk on the people moving platform 170. The vehicle platform 180 may be movable in a vertical direction. The vehicle platform 180 may be used to carry a vehicle. In this way, the vehicle platform 180 may transport vehicles vertically from below the pedestrian platform 170 to the pedestrian platform 170 so that it may dock to the pedestrian platform 170 to be able to rotate with the pedestrian platform 170. In this way, the direction of the head of the vehicle can be turned as required.

When the vehicle loading platform 180 is docked to the pedestrian platform 170, the vehicle transported by the vehicle loading platform 180 is transported into the lobby above the pedestrian platform 170. At this time, a person in the vehicle may enter the hall, and the vehicle may travel in the hall.

Before the vehicle platform 180 is moved to the pedestrian platform 170, the pedestrian platform 170 may be locked to the floor by the locking device 100 to prevent rotation of the pedestrian platform 170 relative to the floor. In this way, the truck platform 180 and the pedestrian platform 170 can be aligned for convenient docking.

Referring to fig. 1 to 3, the locking device 100 includes a lock base 110. The lock base 110 is used for being arranged on a floor slab. The lock base 110 has a lock groove 114 with an opening 115 facing downward.

The locking device 100 further includes a pivot shaft 120, a locking member 130, and a support 150. The axial direction of the pivot shaft 120 is parallel to the horizontal direction.

Support 150 is connected to a man platform 170. In the vertical direction, the locking member 130 is located at the lower end of the man platform 170. The lock 130 is pivotally connected to the bracket 150 by a pivot shaft 120. That is, locking member 130 is coupled to a pedestrian platform 170 via a bracket 150. Thus, the lock 130 rotates between the locked position and the unlocked position. The locking member 130 includes opposite locking and contact ends 134, 133. The pivot shaft 120 is located between the locking end 134 and the contact end 133.

With the locking member 130 in the locked position (the position of the locking member 130 shown in phantom in fig. 2), the locking end 134 of the locking member 130 extends into the locking slot 114 to lock the landing 170 to the floor. At this point, the pedestrian platform 170 cannot rotate relative to the floor.

With locking member 130 in the unlocked position (the position of locking member 130 shown in solid lines in fig. 2.) locking member 130 is clear of lock base 110 to unlock people moving platform 170. In this way, the people moving platform 170 can rotate relative to the floor.

With the locking member 130 in the locked position, the projection of the truck platform 180 on the horizontal plane coincides with the projection of the contact end 133 on the horizontal plane. Thus, during upward movement of the vehicle platform 180, the vehicle platform 180 toggles the contact end 133 from bottom to top, thereby rotating the locking member 130 about the pivot axis 120, and thus rotating the locking end 134 downward and away from the locking slot 114 (when the locking member 130 is in the unlocked position). When the truck platform 180 is docked to the walk platform 170, the truck platform 180 acts on the contact end 133 at all times to hold the lock 130 in the unlocked position.

With continued reference to fig. 2, the locking device 100 further includes a locking spring 140. Locking spring 140 is adapted to be coupled to pedestrian platform 170 and locking member 130 for applying a force to locking member 130 that rotates locking member 130 toward the locked position. Thus, when the vehicle platform 180 moves downward to leave the locking member 130, the locking member 130 returns to the locking position by the locking elastic member 140. The locking member 130 is maintained in the locking position by the locking elastic member 140 before being moved upward to move the locking member 130 away from the locking position.

In this embodiment, in the process of moving the vehicle-carrying platform 180 upward, the locking member 130 is kept at a locking position under the action of the locking elastic member 140, so as to lock the pedestrian platform 170 to the floor, prevent the pedestrian platform 170 from rotating relative to the floor, thereby preventing the pedestrian platform 170 from being staggered with the vehicle-carrying platform 180 and being unable to be docked, further preventing the vehicle-carrying platform 180 and the pedestrian platform 170 from colliding, and preventing the vehicle located on the vehicle-carrying platform 180 and the pedestrian platform 170 from colliding; the contact end 133 is moved upwardly as the vehicle platform 180 moves up to the pedestrian platform 170, thereby rotating the locking member 130 toward the unlocked position, and the locking member 130 remains in the unlocked position as the vehicle platform 180 is docked to the pedestrian platform 170, so that the vehicle platform 180 and the pedestrian platform 170 can rotate together.

Preferably, as shown in fig. 2, the lock base 110 has a notch 116 facing the pedestrian platform 170 in a radial direction of the pedestrian platform 170. Notch 116 communicates with locking groove 114. The locking member 130 is a rod-like structure. Thereby, the structure of the locking member 130 is simple.

With continued reference to fig. 2, the lock base 110 includes two spaced apart recess sidewalls 112, a recess top wall 113 and a lock base body 111. The groove top wall 113 is connected to the top end of the groove side wall 112. Thus, the groove top wall 113 and the two groove side walls 112 form a U-shaped structure with the opening 115 facing downward. The lock base body 111 is a plate. The plane of the lock base body 111 is perpendicular to the radial direction of the man-made platform 170. In the radial direction of the man-machine platform 170, the lock base body 111 is located on the same side of the groove side wall 112 and the groove top wall 113, and is connected to the groove side wall 112 and the groove top wall 113 to form the lock groove 114 and the notch 116. The lock base body 111 is for connection to a floor. Thus, the lock base 110 has high strength and a simple structure.

Preferably, the locking member 130 includes a first segment 131 and a second segment 132. One end of the first section 131 is connected to one end of the second section 132. The pivot shaft 120 is connected to the junction of the first segment 131 and the second segment 132. The free end of the first segment 131 is a contact end 133. The free end of the second section 132 is a locking end 134. The length dimension of the first segment 131 is smaller than the length dimension of the second segment 132. Thus, the locking end 134 is less stressed.

With continued reference to fig. 2, the angle of intersection between the direction of extension of the first segment 131 and the direction of extension of the second segment 132 is greater than 90 ° and less than 180 °. Thereby, the space required for setting the locking member 130 can be reduced.

As shown in fig. 2, the locking device 100 further includes a trigger wheel 160. The trigger wheel 160 is rotatably connected to the contact end 133. Thus, the locking member 130 contacts the carriage platform 180 via the trigger wheel 160. Rolling contact between the trigger wheel 160 and the carriage platform 180 can reduce wear of the locking member 130 and wear of the carriage platform 180.

It is further preferred that the outer surface of the touch wheel 160 is provided with a wear layer. The wear layer is made of a wear resistant material, such as polyurethane. Thereby, the service life of the touch wheel 160 can be improved.

Preferably, the locking elastic member 140 is a torsion spring. The torsion spring comprises a torsion spring body, a first torsion spring leg and a second torsion spring leg. The torsion spring body is sleeved on the periphery of the pivot shaft 120. The first torsion spring leg abuts against the locking member 130. The second torsion spring leg abuts against the support 150. Thereby, the locking elastic member 140 is small in volume.

It will be appreciated that in an embodiment not shown, the locking spring may also be a cylindrical spring. At this time, one end of the cylindrical spring is connected to the locking member, and the other end of the cylindrical spring is connected to the holder.

The utility model also provides a garage. The garage may be the aforementioned garage. The garage includes the aforementioned locking device 100.

In this embodiment, the garage includes the locking device 100, and the locking member 130 is kept at the locking position under the action of the locking elastic member 140 in the process of moving the vehicle carrying platform 180 upwards, so as to lock the pedestrian platform 170 to the floor, prevent the pedestrian platform 170 from rotating relative to the floor, and avoid being staggered with the vehicle carrying platform 180 and failing to dock, and further avoid collision between the vehicle carrying platform 180 and the pedestrian platform 170, and avoid collision between the vehicle located on the vehicle carrying platform 180 and the pedestrian platform 170; the contact end 133 is moved upwardly as the vehicle platform 180 moves up to the pedestrian platform 170, thereby rotating the locking member 130 toward the unlocked position, and the locking member 130 remains in the unlocked position as the vehicle platform 180 is docked to the pedestrian platform 170, so that the vehicle platform 180 and the pedestrian platform 170 can rotate together.

Returning to fig. 1, pedestrian platform 170 has receiving aperture 171. The receiving hole 171 is a through hole. The receiving hole 171 may have a structure similar to a long hole. Thus, the receiving hole 171 has a first abutment plane 172. The first docking plane 172 is perpendicular to the radial direction of the people moving platform 170. The shape of the vehicle platform 180 is substantially the same as the shape of the receiving hole 171. The vehicle mount platform 180 has a second docking plane 181 corresponding to the first docking plane 172. In the case where the passenger platform 170 is docked to the vehicle platform 180, the vehicle platform 180 extends into the accommodating hole 171, and the first docking plane 172 and the second docking plane 181 are parallel. In this way, the vehicle platform 180 can rotate with the pedestrian platform 170.

Preferably, the garage further comprises a barrier (not shown). The blocking piece is fixedly arranged on the floor slab. In the vertical direction, the stop may be located at the lower end of the pedestrian platform 170. When the man platform 170 is rotated to the predetermined position, the locking end 134 is positioned directly below the locking slot 114. Locking end 134 faces opening 115 of locking slot 114. The stop is located laterally of a portion of the people moving platform 170, about the circumferential direction of the axis of rotation of the people moving platform 170. In this way, the blocking member can block rotation of the pedestrian platform 170. At this point, the carriage platform 180 may be moved downward to clear the lock 130. Thus, the locking member 130 is forced by the locking spring 140 and the locking end 134 enters the locking groove 114.

It is further preferred that the walking platform 170 is provided with a blocking lever. The blocking member is provided with a positioning groove. The blocking rod may extend into the detent to block rotation of the man platform 170.

In an embodiment not shown, the barrier is located laterally of the portion of the passenger platform, around the circumferential direction of the axis of rotation of the passenger platform. The blocking member may be provided at a later-described lifting frame. In this way, the blocking member can block the rotation of the vehicle platform.

The garage also includes a lift drive assembly (not shown) for driving the lift of the vehicle platform 180. The lifting driving assembly comprises a lifting frame, a lifting motor, a chain wheel, a chain and a weight piece. The lifting motor is fixedly arranged on the floor slab. The sprocket is connected to the output shaft of the lift motor. The chain is engaged to the sprocket. The chain bypasses the sprocket. The chain is a non-closed chain. One end of the chain extends downwards to be connected with the lifting frame. The lift is used to carry the vehicle platform 180. The other end of the chain extends downwardly to connect the weight members. Thus, the lift motor is operated to drive the vehicle platform 180 to move up and down.

As shown in fig. 1 and 3, the garage also includes a rotary drive assembly (not shown). The rotary drive assembly is coupled to the pedestrian platform 170 to drive rotation of the pedestrian platform 170 and, in turn, the truck platform 180.

Further preferably, the rotary drive assembly includes a rotary motor 191, a first gear 192, and a second gear 193. The rotary motor 191 is provided on the carriage platform 180. The first gear 192 is connected to an output shaft of the rotary motor 191. The second gear 193 is engaged with the first gear 191. The second gear 193 is connected to the lift below the vehicle platform 180. Thus, rotary motor 191 drives rotation of pedestrian platform 170 via first gear 192 and second gear 193.

Further preferably, the first gear 192 may be a cylindrical gear. The second gear 193 is an external ring gear. The rotary drive assembly also includes a bearing assembly. The second gear 193 is connected to the outer race of the bearing assembly. The inner race of the bearing assembly is coupled to the carriage platform 180. The outer ring lifting frame of the bearing device is connected. However, the inner ring may be connected to the vehicle-carrying platform, and the outer ring may be connected to the lifting assembly. Thus, the rotary drive assembly is simple in structure.

In another embodiment, not shown, the inner race of the bearing assembly may also be connected to the crane. The outer ring of the bearing device is connected with the vehicle carrying platform.

In another embodiment, not shown, the second gear is an inner gear ring, as long as it is capable of driving the vehicle platform to rotate.

It will be appreciated that in an embodiment not shown, the rotary drive assembly includes a rotary electric machine, a first sprocket coupled to an output shaft of the rotary electric machine, a second sprocket disposed on the walkway platform, and a chain engaged to both the first sprocket and the second sprocket.
